Hey Rebecca, I know this because I did a herbal course a few years back and I also have herbal infusions on the go all the time. My infusions always have seepage and oil over run, no matter how tight you close the lid. But - I'm not sure why! Maybe it is because the dried herb expands as it soaks in the oil and creates a larger mass of herbal material and therefore causes excess oil? I've sent off an email to a herbal friend - I will report back.

Why would oil leak out of the jar? Cheers Rebecca On Thu, Jul 29, 2010 at 2:37 PM, Rouse Pauline A <Pauline.Rouse@xxxxxxxxxxxxxx> wrote: I would like to do a Organic infused Chamomile oil. Do I put the dried chamomile into a jar with Sunflower oil and leave for 2 weeks. How much oil would I need? Pauline
